The difference between AC lightning arrester and DC lightning arrester
① AC lightning arrester: AC lightning arrester is used in AC power supply systems, installed on the live and neutral lines of AC power lines to prevent surge voltage from invading along the live and neutral lines, causing damage to AC electrical equipment.
For example, in the past, televisions in rural areas were often damaged by lightning, which was usually caused by lightning surges invading along the 220V AC power line of the television. The general voltage of AC lightning arrester is single-phase 220V and three-phase 380V/420V, etc.
② DC lightning arrester: DC lightning arrester is used for protection in DC power supply systems, installed on the positive and negative poles of DC lines to prevent surges from entering the DC system and causing equipment damage. The application voltage of DC lightning arrester generally includes 24VDC, 48VDC, 220VDC, up to 1500VDC, etc. The voltage of DC lightning arrester ranges from low voltage 5V to 1500V, with a large span and a variety of types.
